parts the fur is of a faded brown colour for the greater part of its 

 length, but near the tip it becomes a little darker, and is finally 

 tipped with dirty buff colour. The fur on the membranes beneath 

 the humerus is in some examples of the same tricolour as the under 

 parts of the body, but more frequently it is of a uniform brownish- 

 yellow hue, as is that beneath the fore-arm, and that at the base of 

 the fingers. 



The hairy portions of the membranes are reddish-brown ; the 

 remaining parts very dark brown. 



The variations in colour to which this species is subject depend 

 upon the tint of the brown colour near to the tips of the hairs. In 

 one example in the British Museum, this part of the hair is of a 

 light red colour, inclining to pinkish, and takes up a much greater 

 space than usual in each hair, the dusky at the base being there 

 very much reduced. In this specimen the black of the face and the 

 yellowish colour of the throat are scarcely observable ; and this, with 

 the red colour, gives it, at first sight, a great resemblance to the 

 L. noveboracensis. 



The colour of the fur is an index to that of the membranes — in 

 this instance a reddish-brown. 



The dentition has not been well examined, but the incisors are 

 similar in number and shape to those of the last two species. 



Five examples have been examined in drawing up the above de- 

 scription, and these are all so remarkably uniform in size, that it 

 appears unnecessary to give the dimensions of more than two, those 

 presenting the greatest disparity being selected.

The dimensions in column No. 1 have been taken from a perfectly 

 adult individual in the British Museum, the locality being unknown. 

 The specimen which has furnished the dimensions in the second 

 column is also full-grown, but nevertheless retains some indications 

 of youth.
